De Neef Product Pail

Grace offers chemical grouts, specialty injection resins and over 40 years of technical experience in their use. For the civil market this includes polyurethane grouting products (also called PU grouts) and acrylate resins for leak remediation, curtain wall grouting, slab stabilization and slab lifting.  Grout contractors can approach these problems through either injection or soak and place methods. In the municipal market Grace offers chemical grouting products for the grouting of mainline and lateral sewers, manhole remediation and repairs to storm pipes, box culverts and water tanks. These chemical grouting solutions can be applied with remote packers, by dill and place methods or by direct injection into soils. To serve the geotech market there are a wide range of rigid polyurethane chemical grouts, acrylate gels, and microfine cements to solve soil improvement issues, groundwater remediation problems and support of excavation challenges. A grouting contractor who uses down-hole packers, strainer pipes, or through wall installation techniques will find Grace's De Neef® grouts versatile and effective.

For tunnels and dams, Grace offers a wide range of De Neef products for specialty applications such as TBM pre-grouting, rock stabilization, void filling, and groundwater control. Whether the grouting contractor is looking for a groundwater controlling gel, a soil stabilizing microfine cement or a two component polyurethane grout, DeNeef grout is the solution. In addition to these leading edge technologies, Grace has the technical expertise to help the grout contractors apply these chemistries to the specific challenges of your project. It is this commitment to solving problems on every that sets the Grace technical specialists a step above the rest.
