If your concrete slab already has poly sheeting under it (it probably does if it was poured in the 90s), you don't need to worry about adding a dedicated vapor barrier. So regardless, don't worry about "sealing" the concrete. Anyway, most closed-cell foam engineered flooring underlayments already constitute a vapor barrier, and that's probably okay even if ...

I have had 3/4" hardwood floors placed on Dricore on 2 different jobs. One below grade with a foundation drain system the company I worked for installed. Top of the line, no holds barred water control system. The floor went down a is still performing beautifully. 1 1/2" staples were used so they did not go through the plywood so far to poke holes in the ...

Concrete absorbs water. That’s why it can never be finishing layer in this type of situations. Even if it is properly tilted that wouldn't solve your problem completely. You must protect it. Now, if you want to do it right it's a bit more complex than just putting tiles. If you are short on money you can do just that but it's not proper solution. Firstly you ...

You have to jack the porch up to get it back to the correct height. I would suggest using a level to hold at a congruent part of your roofline or front molding. Take a car jack and a 4x4 and prop the roofline until it is a bit higher (1/8") than level. Slide under some pressure treated wood or rubber shims under the posts. Check in local rafters, ...

Forget the porch, it is a goner. The important thing is to support the roof. You need to create a footing for the pillar (or pillars) that is/are holding up the roof. Dig 6 feet down minimum make a bed of gravel. Insert a concrete pillar form (you can get them at Home Depot). Pour concrete into form. The footing should be 6 feet or more under the surface of ...

For mechanical removal of paint from floors.... If you're talking about drips/splatters/spills that are on the floor from painting the walls/ceiling you can use wire or bristle disks that are meant for removing paint/rust and there's also the Wagner Paint Eater. If you're talking about the whole floor covered in paint you can rent a floor sander with an ...

I’m guessing that slab is on the ground floor .If so, and then from my experience it is much cheaper and easier to make a new than to fix the old slab. Firstly, you should smash the old one and then check groundwork under the slab. If it is not quality (well compacted) then you should pour some Breakstone, gravel and compact it as much as possible. Then you ...

Concrete will deteriorate over time depending on the mineral content of the soil that is in contact with the concrete. Removal of the entire pour is not required or recommended. This would be costly and time consuming. The areas that sound hollow will have to be removed. These areas act like a cancerous pocket and will harbor the moisture that is partly ...

Use your "second thought" comment for your placement of the joints. With your faucet in mind you can lay a 3/16" or 1/4" diameter stainless steel rod at the front edge and two on the back edge oriented around the faucet layout. DO NOT use the standard steel rods you get at the big box stores. They will rust and pop the concrete! Make sure the rods go past ...

You use plasticiser when you need to improve the workability of concrete. Concrete's workability improves as you add increasing amounts of water. Increasing the amount of water in the mix beyond the optimum leads to weaker concrete. Insufficient water also makes concrete weaker, as it is harder to compact it to remove air voids. For a normal floor slab, I ...

I can't see the pictures as clearly as the others but based on what you said there could be a small stream running under your basement. I had a couple of friends that had this problem and to solve it they both used different solutions. The one friend had a side that he could direct the water outside so he made a trench with the pipe they use in french drains ...

Try a tanking slurry product like KA tanking slurry , uselly used in basements, brushed onto the concrete floor. The correct method as previous poster mentioned would be to remove the concrete floor and install a proper dpm.
