When a lot of fill, several feet or more in depth,was required to bring the slab to the desired height, there wasa good chance that the slab would settle or tip in the future.Garage slabs which were poured inside of the foundation walls butwhich were pinned to the foundation sides (typically usingre-bar set into holes punched into the masonry block foundation),the slab was resistant to settlement or movement even if therewas modest soil settlement below.In a garage where the slab has settled you can often spot the originallevel of the slab and thus can measure the amount of settlement.
Typically a thin film will form on a crack filler epoxy in 8 hours, the sealant will be hard enough to withstand traffic in 24 hours, and it will fully cure in about a week.These notes are based on epoxy product application information available from Lone Star Epoxies.Use of Polyurea as a control joint filler or crack sealant in concrete slabs (Polyurethane Foam Injection Method) Polyurea joint filler products for concrete control joints have received attention for filling concretecontrol joints and is increasingly used in that application since this material is resistant to moisture, has high adhesionproperties when used with concrete, and will cure in very cold weather.Polyurea sealant products are also reported to be usefulin sealing control joints in "green" concrete which has not yet had its full 28 day period of initial curing.An advantage of polyurea or polyurethane used as a crack sealant is that the flexibility of the material will accommodate slight seasonal or temperature-related movement that might otherwise cause new cracks in an epoxy-repaired structure or reopening of repaired cracks in a mortar or concrete-repaired crack.Also in our experience, because the injected polyurethane foam expands after it is injected into a crack, you may find it easier to fill the crack through the building floor slab or wall than when using alternative repair methods such as epoxy or masonry repair kits.Carson Dunlop Associates' sketch (left) illustrates foundation wall crack repair using epoxy or polyurethane injection.List of materials, product sources, how-to for polyurethane foam crack sealant See our separate article Polyurethane Foam Injection for details of the procedure for using polyurethane foam to seal foundation cracks and for a list of sources & brands of polyurea or polyurethane foam sealants, caulks, and crack repair kits.
