In this video I am going to show you how to build a deck right over an existing concrete slab! If you have a concrete slab that is in good shape it is very e.. The failed waterproofing is causing major structural damage to the concrete structural slab below these areas, the report continued, adding that under the pool deck where the slab had been. .
A concrete landing is simply a concrete slab that can act as your first step on the stairs and also provides a flat and stable base for people that use the stairs. However, before you install a landing at the base of deck stairs, there are some things you should understand about good concrete landing design and how a concrete landing can help. This allowed the sleeper (the 12-foot 2×4) to lay atop them and be level. Any rain that hit the deck would run through the gaps in the decking onto the concrete below, and continue to flow down the slant to the grass, as intended. The PVC spacers would keep the 4×4 blocks from sitting in any water As the concrete slab cures, the metal deck and the concrete bond together to create a composite metal floor deck. This is the most common type of metal floor decking. The main advantage of a composite metal floor deck is that it will increase the strength of the floor without adding extra weight Documents submitted to the town as part of permitting and construction show the deck slab, which makes up the ceiling of the underground garage, needed 500 feet of cracks sealed and a 20-square.
Concrete Foundation. A concrete slab is the most durable, stable and most recommended foundation for a spa. While it is the most expensive of the four options shown here it is by no means unaffordable. It can be formed in many shapes, the minimum thickness we recommend is 4 inches with rebar reinforcements This article shows how to build a 4-in. thick slab that will serve as a foundation for a set of deck steps. Be prepared for a workout if you're constructing a concrete slab. It can be tough work, requiring a lot of digging, mixing and other sorts of manual labor. Step by Step. First, mark the perimeter of the slab location with stakes and string How to build a deck over a concrete slab. Step 3 - Inserting the Hex Bolt. Insert 10mm hex-bolt through base plate. AJ45KIT is designed to provide a top of the joist height from 86mm using 100mm length fully threaded bolts + 70mm x 45mm joists to 150mm + 90mm x 45mm joists.. AJH45G is designed to provide a top of the joist height from 86mm using 60mm long bolts + 70mm x 45mm joists to. Under-Deck Ceilings. A number of recently introduced under-deck ceiling systems use corrugated aluminum or plastic panels designed to catch water that drains through decking and channel it away from the area below. Among the newest is the RainTight system, introduced at Deck Expo 2014. RainTight panels are made of heavy-gauge aluminum
Step 5 - Place the Mesh. Reinforce the concrete with 6×6-10/10 wire mesh. Put the mesh on wire supports, sold separately, so it sits roughly in the middle of the slab's thickness. Leave a few inches of space between the mesh and the edges of the forms to prevent rust If you try to set the support posts on top of a patio slab below it is very likely to crack and break your patio concrete slab. You would have to have it much thicker and steel reinforced. But that is just the wrong way to do it. Dig and pour a proper footing for the upper deck support posts and then pour the patio slab after Deflection of Composite Deck Slabs in Concrete Construction, September 1997; and ACI 302.IR-04, Guide for Concrete Floor and Slab Construction. ASCC concrete contractors will work with all parties in addressing these issues. If you have any questions, contact your ASCC concrete contractor or the ASCC Technical Hotline at (800) 331-0668
. Approximate deck dimensions are 20' X 10'. I'll be laying some fabric and gravel to kill off any vegitation under the deck area. I'm really not sure how to proceed with getting the deck foundation set up, or how to properly estimate the height of the deck and the materials I'll need The truth about decks built over concrete slabs. Although it is not impossible to install a deck over a concrete patio, it is uncommon. This is because concrete patios rarely offer enough space over which to install a deck. Furthermore, concrete patios are usually an extension of the concrete slab foundation on which your house is built, and. for the concrete during construction, but also as the principal tensile reinforcement for the bottom fibers of the composite slab. The term composite steel deck floor slab is applied to systems in which the steel deck has some mechanical means of providing positive interlocking between the deck and the concrete Three years before the collapse, a consultant found evidence of major structural damage to the concrete slab below the pool deck and abundant cracking and crumbling of the columns.
Yes, you should put a vapor barrier under concrete slabs to prevent moisture from wicking up into the slab and onto the surface of your concrete slab, patio, or driveway.Ensure the vapor barrier is above both the gravel and rigid foam and immediately below the slab. Moisture wicking up into a slab can cause unsightly wet spots on top of your slab, and the efflorescence can be hard to remove precast concrete, partial precast concrete ,Exodermic panels and steel plate sandwich (SPS) panels were evaluated. An innovative design of full depth, precast prestressed concrete deck slab panels for use in new as well as replacement bridge decks, is described.

Lightweight concrete composite slabs are inherently more efficient than normal-weight composite slabs with nearly identical structural characteristics and design strengths. Concrete slab-on-metal deck thicknesses are typically controlled by fire-rating requirements as opposed to strength requirements . Steel decks for composite deck-reinforced floor construc tion are commercially available in a variety of shapes and sizes. They normally consist of cold-formed corrugated sheets or ribbed panels to provide adequate strength during the con struction stage The most common causes of pool deck movement and other issues: Poor Pool Construction: When the pool is constructed, the backfill material may not be properly compacted. As a result, the soil settles and creates voids under the pool deck. Heavy Concrete Slab: Heavy concrete slab around the pool can cause loose soil to compress under the slab.
A concrete slab suspended in between two beams will experience tension on the underside of the slab when you put weight on top of the slab. This same issue holds for ceramic tile, stone. Composite slabs consist of profiled steel decking with an in-situ reinforced concrete topping. The decking not only acts as permanent formwork to the concrete, but also provides sufficient shear bond with the concrete so that, when the concrete has gained strength, the two materials act together compositely A good way to understand what kind of forces a concrete deck is exposed to, is to see the deck as an board which ends are placed on two pallets. A properly executed concrete slab will not crack. We warranty this in our contract even on cantilever patios. These are the steps we take: Yes it cracks under the control joints
bubbledeck slab is designed exactly the same way as the solid slab. 275 B) Bending strength Bubble Deck when compared to a solid deck, both practically and theoretically. The results in the table below shows that for the same deck thickness, the bending strength is same for Bubble Deck and for a solid deck and that the stiffness of th Prior to placing concrete forms: Construct the form with 2x4 or 2x6 lumber and secure in place by wood stakes and deck screws. Excavate the slab area to a depth of about 7 inches, allowing 3 inches for a gravel base and 4 inches for concrete. Step 2 Check the forms for level (¼ inch for every 12 feet is sufficient to allow for rain run-off) However, heat is transferred directly into the concrete due to the deck plate rib and Y-shape flange, and the internal temperature of the slab rises compared to the general RC slab. As a result, the water vapor pressure is greater than the internal stress of the concrete, causing spalling [ 4 , 5 ] Where an interior concrete slab-on-grade is provided and is in contact with the interior surface of the foundation wall, measurement of the unbalanced backfill height from the exterior finish ground level to the top of the interior concrete slab is permitted. d. Solid indicates solid masonry unit; grout indicates grouted hollow units. e Add a fence that sits adjacent to an exisiting concrete slab or pool deck Or, maybe you just want to eliminate of the hassle of weedeating under under the privacy fence around your house .

The structural slab system used to support plaza decks can be any one of the basic slab designs. The 2-way flat plate was the most common historic slab system use for plaza decks. This was followed later by the one-way slab over beam systems, which were also common for plaza deck support The obtained results of the strain in metal deck are illustrated in Fig. 29 in the form of bar chart for two types of concrete slab strengthened with FRC and metal rebar under sequential impact loading. Moreover, by applying the impact loading the maximum amount of the strain was increased in specimens
The steel girts are flown into place with a crane. On top of the steel frame we lay out a metal pan deck to support the concrete slab. Each pan-deck panel is 36 in. wide with six 3-in.-deep corrugations. The panels click together with a male and female seam on each panel. The seams can be field welded or crimped—we chose welding But even more importantly, if weak soil caused the slab to sink, the soil may compress again under the weight of the new slab. A shortcut repair -adding more concrete to even out the slab—imposes even more weight on the soil, increasing the risk of sinking in the future. PolyLevel® can repair your sinking slab quickly & effectivel
The Midwest Roofing Contractors Association (MRCA) is advising a vapor retarder of less than 0.01 perm is necessary over new concrete roof decks. From a practical standpoint, a vapor retarder of less than 0.01 perm is effectively a vapor barrier—almost no moisture passes through to the roof system above. This method is shown in the image above If you're pouring a 5 inch thick slab for a driveway, sidewalk or patio, just be sure there are at least 1.5 inches of concrete that will flow under the steel Inspired by Neo19 's deck, Bunnings Workshop member Brendon_B built this 5600mm x 2000mm deck over a pebblecrete slab using 140 x 199mm Merbau. Bunnings Workshop member Usman built a 11 x 3.5m deck over concrete, with plans to cover the area with bistro blinds from Bunnings. Tags Bridge deck cracking is a common problem throughout the United States, and it affects the service life of concrete bridges. Several departments of transportation (DOTs) in the United States prefer using continuous span structural (CSS) slab bridges without stringers over typical four-lane highways or steams. The primar Deck Types Roof Deck • Permanent Structural Member • No Concrete Topping Composite Deck • Deck and Concrete Work Together • Embossments - Composite Action Form Deck • Deck is Permanent Form • Deck Often Carries Slab Weigh
A slab of concrete, otherwise known as poured concrete, is poured onto your driveway, deck, patio or other outdoor surface. It's about 4 inches thick, making it incredibly durable. Concrete slabs are a popular choice if you're looking for low cost of material ( $6 per square foot including labor) with minimal maintenance structural concrete slab supported by the structural steel frame and the concrete topping slab above (Fig. 5). The objective of the analysis was to study the effect of the link properties (that is, stiffness) Fig. 1: Typical components of a plaza deck system Fig. 2: Cracking and concrete spalling of topping slab (plaza deck system
Wood is a much weaker material than concrete and steel, the idea of wood carrying metal deck with concrete on top of the deck is the equivalent of a dog carrying a horse. Let's figure out if you're getting a fair estimate for your project. A 24ft x 24ft garage floor is 576 square feet. Typical floor thickness like this will be 6 inches thick The more immediate problem is the washout under corner of slab outside the basement door. The slab runs the width of the house under deck. One corner of the slab is hanging out in mid-air because the 1st terraced area has subsided about 6 -- This is my father-in-law's house and I have no idea how long the area has been washed out. The concrete slab foundation has a crack in it the total width of the house. You can see it from the outside and it travels from there through a bedroom through the family room under the fireplace to the other end of the house I am not so sure you can span 14' with a concrete slab over a steel deck without some additional support underneath (see website page below). As far as how to model this, you should be able to reproduce the profile of the steel deck material as well as the concrete material on the steel deck
Concrete slab floors. Concrete slab floors come in many forms and can be used to provide great thermal comfort and lifestyle advantages. Slabs can be on-ground, suspended, or a mix of both. They can be insulated, both underneath and on the edges. Conventional concrete has high embodied energy Otherwise the concrete slab and borders will be exposed and will not look good. This amount of material could cause problems itself. The Finished Product Depends on What's Underneath. Third, installing paving stones over a concrete slab may be easier, and thus within the skill of a homeowner, the finished product may be somewhat disappointing The deck may have dropped down for many reasons: including poor compaction, settlement or an under-slab leak. Using the slab jacking process, contractors may be able to raise all or some of the sections of the deck back to their original elevation. Photo shows a concrete deck that has dropped about 3 inches next to the pools copin composite steel deck appear to be based on a desire to hasten the drying time of the concrete that is cast on the deck. Problems with the application of flooring on concrete slabs have been reported on concrete slabs cast on varied concrete substrates, including slab on grade, suspended slabs, and slabs cast on steel deck
Additional support must also be placed under the deck to support the additional weight of the porch, as well as any snow that may accumulate in northern climates. In many instances, however, the porch will be constructed on a concrete or other type of solid patio. The ideal scenario is to pour a concrete slab for the porch, which can then be. Use your jigsaw. Notch out the bottom front of the center stair stringers to accept a 2x4 base plate. Make sure your stringers are level. Fasten the base plate to the stair stringers with screws. Locked in place. Use a hammer and drill to install 1/2 x 3 sleeve anchors through the base plate into the concrete pad If you have the room you could dig down the depth of an edging stone or cinder block, what ever will fit in the space between the concrete and the deck and another 2 of screening for drainage. Put the screening in 2 deep under the edging stone or cinder block and place them along the edge leaving a 1 gap between the stone and the concrete
Figure 3. Concrete paver (left) and a concrete paving slab (right): similar paving products with varying applications for roof decks. Figure 4. Some ballast-type slabs for roof decks are made with lightweight concrete materials. They can be joined with tongue-and-grooves and/or with connectors to resist wind uplift A permit dated May 17, 2021, for $1.1 million in roof maintenance included removing the existing roof system down to the concrete deck, priming the deck with asphalt primer, demolishing the. However, the usual thickness of a concrete slab is around 10 cm. Whatever you plan on doing, your concrete slab should be at least 5 cm thick. That is the bare minimum of a concrete slab thickness. This is the thickness of the concrete slab alone and it doesn't include the gravel base, if you are using something like that
Mudjacking is a method of lifting a sunken concrete slab by pumping a mud-like mixture under the concrete to make it level again. Mudjacking, also known as slab jacking or concrete leveling, is a quick and cost-effective way to level sinking concrete foundations, sidewalks, patios, and driveways GPR can help with: Pinpointing structural elements in concrete such as. Rebar. Post-tension cables. Metallic and non-metallic pipes and conduits. Wire mesh. Locating conduits (plastic & metallic) and in-floor heating lines in concrete, or just below a slab-on-grade. Measure the cover depth of embedments. Map rebar and rebar patterns Across the US, homeowners report that ready - mix concrete costs about $98-99 per cubic yard. The average cost of a concrete slab (6 inches thick) is $5.00-5.50 per square foot, including materials and labor.However, the price can go up to $9-10 per square foot depending on numerous factors and enhancement costs.. Thus, your cost to pave a 2-car driveway of 16 feet wide, and 40 feet long. Different types of concrete slab. A standard 10x10 concrete slab will usually cost from $670 to $930, but not all slabs are priced equally. The thicker the slab, the more you should expect to pay, so the cost of a concrete slab for a shed will be less than a concrete slab for a house, because it will won't be as thick This mud is injected under the concrete slabs, oftentimes using a movable pump that can access most slabs. Once the void under the slab is filled, the pressure builds under the slab, lifting the concrete back into place. Once in place, the holes are filled with a color-matching grout
Islam (1996) investigated the behaviour of reinforced concrete skew slabs designed for axle loading and self-loads at service condition. Experimental investigation was carried out on 30 degrees skew slab with an aspect ratio of two-third. The right span was 16 ft and right width was 24 ft. Four skew slabs were tested
