Services
Gypsum Concrete Installation
Gypsum concrete installation provides durable, crack-resistant underlayments ideal for radiant heating systems. This material offers superior thermal conductivity, faster curing times, and higher compressive strength compared to traditional concrete. Our team ensures precise application for both residential and commercial projects.
Radiant Heat Systems
Radiant heat systems embedded in gypsum concrete deliver efficient, even heating for homes and businesses. This solution reduces energy costs while enhancing comfort through superior thermal mass properties. We specialize in hydronic and electric system integration.
Floor Leveling
Floor leveling services address uneven surfaces using gypsum concrete or cementitious self-levelers. We correct slopes and sagging in both old and new structures, creating flat bases for flooring installations without compromising structural integrity.
Decorative Finishes
Decorative cementitious toppings add aesthetic appeal to gypsum concrete underlayments. Available in polished, stained, or textured finishes, these lightweight coatings mimic concrete aesthetics without requiring structural reinforcement for wood-framed buildings.
Lightweight Concrete Solutions
Lightweight concrete applications provide fire resistance and sound control in multi-family structures. While phased out for radiant systems, we still utilize this material for specific insulation needs where thermal efficiency is less critical.

Questions
What is Gypsum Concrete and why is it better for radiant heat?
Gypsum concrete is a cementitious material with superior thermal conductivity and crack resistance. It outperforms lightweight concrete by providing even heat distribution, faster curing, and higher compressive strength.
Can you level uneven floors in older homes?
Yes, we use gypsum concrete or cementitious self-levelers to correct sloped or sagging floors in both new and older structures, ensuring a flat, stable surface.
Do you work on commercial projects?
Yes, we handle projects of all scales, from multi-story commercial buildings to residential spaces, with expertise in soundproofing and radiant heating systems.
What are decorative finished floors?
Decorative cementitious toppings applied over gypsum concrete to mimic concrete aesthetics without structural reinforcement, offering polished, stained, or textured finishes.
How long does gypsum concrete take to cure?
Gypsum concrete dries faster than traditional concrete, typically ready for flooring installation within 24-48 hours depending on thickness and conditions.
What areas do you serve?
We serve Monroe, Seattle, Bellevue, Mercer Island, and surrounding areas in Washington State for all flooring and radiant heat projects.
