Versatile Solutions for Construction Professionals

Our catalog of Compounds & Chemicals supports every phase of a concrete or masonry job. From prepping and pouring to finishing and repairing, we supply industry-grade solutions that help you meet deadlines while achieving top-tier results. We understand that contractors, masons, and builders rely on the right chemical additives to adapt to changing jobsite conditions and project demands.

Accelerators for Faster Set Times

When cold weather or tight schedules demand faster curing, concrete accelerators are a vital tool. These Compounds & Chemicals increase the hydration rate of cement, speeding up the setting process without sacrificing strength. They're particularly useful during winter months or for time-sensitive pours that need to be ready for the next construction phase quickly and safely.

Curing and Sealing Liquids for Surface Protection

Maintaining proper moisture levels is crucial in the early stages of concrete curing. Our curing and sealing products lock in hydration, helping reduce surface cracking and ensuring a consistent, durable finish. These Compounds & Chemicals form a protective barrier, shielding new concrete from weather exposure, dust, and premature wear.

Form Oils for Clean Release

For contractors working with molds and formwork, our premium form oils make demolding smoother and safer. These specialized Compounds & Chemicals prevent bonding between concrete and wood or metal forms, reducing surface blemishes and lowering cleanup time. They help preserve the lifespan of your formwork while improving the quality of the finished product.

Concrete Compounds for Repair and Bonding

Whether you need to fill surface imperfections or attach new concrete to old, our bonding compounds are formulated for high-performance adhesion. These repair Compounds & Chemicals offer long-lasting structural strength for everything from small cracks to large patchwork applications. Easy to mix and apply, they’re engineered for both durability and worksite efficiency.

Self-Leveling Caulks and Adhesives

Uneven surfaces, gaps, and joints require precise treatment to ensure waterproofing and stability. Our self-leveling caulks and adhesives are ideal for such tasks, flowing smoothly into gaps and creating a clean, uniform seal. These Compounds & Chemicals are perfect for interior and exterior concrete seams, expansion joints, or any transition area that requires flexibility and protection.

Concrete Epoxy for Industrial Strength

For maximum bond strength and resistance to impact or moisture, our concrete epoxy products offer unmatched durability. These Compounds & Chemicals are used in both structural and decorative applications, including anchoring, crack filling, and overlaying. Whether you're sealing garage floors or reinforcing heavy-use walkways, epoxy resins are an essential addition to your toolkit.
