Crawl Liner Encapsulation vs. Concrete Crawl Floors

I was recently asked about the pros and cons of crawl liners and concrete crawl floors. Considering that we have had many years of experience installing both of these systems I feel that Atlas Restoration is uniquely qualified to answer this question.

The main issues (i.e. problems) with pouring concrete in a damp and musty crawlspace are as follows:

  • Concrete does not effectively stop the musty smells (this is usually mold by the way).
  • Concrete does not effectively stop the moisture and humidity from entering the home.
  • Because concrete absorbs water (look at the dark spots in wet concrete sometime) it soaks up the moisture from the soils underneath it, effectively defeating the purpose of crawl space remediation in the first place!!! One technique to try and overcome this inherent flaw is to place plastic liner down before the concrete is poured. The problem with this is that the thin plastic liner tears quite easily when the concrete is put on top of it without the installer’s knowledge.
  • Concrete does not have any insulating benefits – it will cost the same to heat and cool your home after the installation of a concrete floor. 
  • The installation time for a concrete floor in a crawl space is not limited solely to the two or three messy days involved with the pumping process. Because the crawl space is already damp and musty, it can take weeks for the concrete to actually cure!
  • Unless it is heavily reinforced, concrete will always crack. It is not a question of if, but rather when the concrete will crack – sooner or later leaving the homeowner in the same situation they were in originally! A crack in the concrete lets in the same water, mold, mildew, bugs and soil that are inherent in an unprotected crawl space.
  • Believe it or not, with all of these issues concrete is usually significantly more expensive than a liner system. For these reasons and more Atlas Restoration primarily installs Hydraliner crawlspace liners.

Just some of the advantages of the Hydraliner are as follows:

  • Does not absorb moisture
  • Seals the crawlspace walls as well as the floor, keeping out rodents and insects
  • Seals out the musty crawl space smells
  • Completely insulates the crawlspace, virtually paying for itself in heating and cooling savings
  • Will not crack or break
  • Tough and puncture resistant. You can crawl on it, service technicians can crawl on it, and you can store any item on it. Hydraliner will transform your former unusable crawl space into a clean, dry, and ample storage space for your home.
  • Bright white finish actually brightens a crawl space with limited light, creating a friendlier storage environment
  • Hydraliner comes with a 25-year, fully transferable warranty!

Atlas Polyurethane Slabjacking

Atlas Polyurethane Slabjacking is a process of injecting a high-density polyurethane under a slab to build up pressure and hydraulically lift the slab up to its original position. To learn more about Atlas Polyurethane Slabjacking click on this link:

How To Eliminate Concrete Slab Curling

Here's how Atlas Restoration tackles concrete slab curling:

  • Movement is precisely measured at joints to assess severity of curling. Straight edges are also used to determine amount of curl. Movement greater than .015 inches is severe enough to cause deterioration three to four times as fast as normal. Restoring sub grade support is the key to the repair.
  • Holes are drilled on each side of the joint where curling has occurred.
  • A high-density polyurethane grout is pumped in under low pressure to fill voids beneath curled edges.
  • Surface restoration consists of removing the distressed concrete, reconstructing slab edges with polymer concrete and reestablishing the joint. These repairs often include grinding the surface to improve rideability and replacing damaged joint sealant material.
  • Work is most commonly done at night and on weekends to avoid disruption to normal warehouse operations.

Concrete Slab Curling

Curling is one of the most common defects found in a structure's floors. Slabs curl upward at joints, saw-cuts and edges. As forklifts pass over the joint, this loss of subgrade support causes slab movement. Joint edges deteriorate, cracks in the slab develop and wires embedded in concrete for automatic guidance systems may break. The amount of differential movement from one side of the joint to the other is directly related to the speed of floor deterioration.

Is The Crack In My Basement or Crawl Space A Sign Of A Structural Problem?

At Atlas Restoration we see thousands of cracks a year, the majority of which are not the result of structural movement. Most cracks are simply shrinkage cracks that are subject to seepage but pose no structural threat to your home. Untreated, however, some cracks can cause severe damage to the structure.

Here are some of the telltale signs of a crack problem in your home:

  • Visible cracks are significantly wider at the top than at the bottom; the crack is offset and not on a smooth plane
  • Cracking in interior walls in the upstairs of your home
  • Doors or windows in your home don't shut easily 
  • Exterior brickwork of your home is cracked or bulging
  • Floors in your home are not level
