The power of polymers Differentially settled concrete walks causing trip hazards? Settled gymnasium floors? Uneven office/classroom floors? Entrance, foyer and hallway floor settlement? Negatively sloped walks and concrete paved parking lots? Do you have any other slab-on-grade concrete settlement issue or void condition? We have the solution! Over the past 14 years, Poly-Mor Canada has been employing an array of expanding polymer resins to lift settled concrete slabs, fill voided areas, stabilize weak base soils strata and leak seal infrastructure challenges. The Poly-Mor process is fast, clean, precise, environmentally friendly, non-intrusive and cost-effective. How is it done? Poly-Mor’s proprietary expanding polymer resin system, in its liquid state, is injected between the concrete slab and the base soils through drilled holes 5/8-inch in diameter (15 mm or the size of a penny). The material immediately (within seven to 14 seconds) fills any voids, and then accurately and controllably lifts the settled slab to its proper elevation. The expanding resin exerts a force of over 10,240 pounds/square foot (50 tons/square metre) and the lifting is monitored using zip-levels or laser levels. The causes for concrete slab settlement and subsidence are many. The following are the most frequently suited to the Poly-Mor remedial technology: 1) Inadequate compaction of base soils during initial construction, predominantly evident around perimeter foundations with resultant walk settlement and negative slope towards the building. 2) Drying out or desiccation of base soils where the moisture in the base soils evaporates and causes shrinkage of the base soils. 3) Leaking water pipes or broken 64
