D u r a – C a p ® F l o o r Underlayment (commonly known as “Gypcrete”) is a nonstructural gypsum concrete used with aggregates in pouring crack resistant, fire resistant and sound-insulating floors. Batch mixed on the job, barrel mixed or pumped into place by authorized applicators, it is ideal over veneer and non-veneer wood subfloor panels, precast concrete and cast-in-place concrete. With proper preparation, Dura-Cap® Floor Underlayment (Gypcrete) can accept virtually any type of flooring material.

Watch the following video which gives general instruction for installing Infloor Heat and Gypcrete. The Infloor heat is installed first, whether it is electric radiant heating cables or hydronic (hot water) tubing. The Gypcrete is self leveling and provides a very smooth and level floor and the Infloor Heating adds the warmth so you finish up with warm, level floors!!
