Enhanced Slab On Grade LASRE Slab System
The Low Anticipated Swell-Radon Evacuation (LASRE) forms create a low-profile concrete slab for low swell conditions where no movement can be tolerated. This system eliminates the need for underground pipe and gravel.
About LASRE Forms
✔️ Useful where native soils have been excavated and re-compacted
✔️ Allows for swell potentials up to 1.5%
✔️ LASRE forms on basement sub-grade take the place of normal backfill
✔️ Increased dead load better resists soil heaving
✔️ Continuous air chambers allow for radon to be removed and vented with a pipe
✔️ No need for underground pipe and gravel systems
Specs
Concentrated dead load of 1,054# per square foot (typical slab on grade is 50#)
Expansion is contained within 10” tall air chamber
