Concrete and yard slabs

From warehouse floors to outdoor yards, we provide specialist mastic and sealant solutions for concrete slabs and expansion joints. Our applications are built to endure traffic, temperature shifts, and moisture protecting your surface for the long term.

Built for Movement, Backed by Experience

Concrete expands and contracts with temperature, moisture, and load making high-quality joint sealing essential. At Mastic Works, we don’t just fill the gaps. We assess substrate condition, movement needs, and environmental exposure to apply the right solution with care. Whether for new pours or resealing existing slabs, our team delivers clean, durable work that stands up to the pressure.

Precision Where It Matters

Heavy-Use Ready

Our sealants are built to withstand high traffic, constant movement, and extreme weather. Perfect for loading bays, warehouses, and industrial yards where durability is critical.

Expansion Joint Expertise

We understand how concrete behaves. Our team expertly seals expansion joints to manage shrinkage and thermal shifts reducing cracking and long-term maintenance.

Clean, Level Finishes

Neat, flush applications that don’t just perform well they look the part too. We help preserve clean surfaces and easy-to-use working areas across interior and exterior slabs.

Interior Sealant FAQs

What types of concrete joints do you seal?

We seal a wide range of joints, including expansion joints, construction joints, and saw cuts both indoors and outdoors. Each type is treated with the correct material and preparation for long-term durability.

Are your sealants suitable for heavy traffic areas?

Yes, we use high-performance joint sealants designed for areas subject to forklifts, trolleys, and regular vehicle movement. They maintain flexibility while resisting abrasion and weathering.

Can you work around operational sites or live environments?

Absolutely. Our team is experienced in working with minimal disruption, whether it's an active warehouse, logistics yard, or construction site.

How long does the sealant take to cure?

Cure times vary depending on the product and conditions, but most are traffic-ready within 24 hours. We’ll advise on exact timings once the site assessment is done.
