Durable, high‑strength epoxy mortar that resists cracking and staining—keeps gravel locked long‑term.

Eco-friendly epoxy mortar lets water pass through, boosting durability in freeze/thaw climates.

It withstands heavy traffic, moisture, UV, and chemicals. It is ideal outdoors and keeps projects looking great.

High UV resistance prevents degradation, keeping projects durable even in constant sun.

One-part resin sands handle pedestrian areas and narrow joints. Two-part epoxy mortars are built for medium to heavy vehicular traffic, driveways, and wide joints. Concrete additives boost standard bagged concrete for custom paver edging, while trass bedding mortars and bonding slurries create stable, permeable bases for heavy stone or porcelain.
Most resin and epoxy joint compounds can be installed on damp paving and during light rain. Bedding mortars, bonding slurries, and concrete edging mixes need dry weather during application to set correctly.
Higher temperatures speed up curing and shorten your working window to about 30 minutes, so work quickly and clean surface residue off immediately. Cooler temperatures slow curing down. Do not apply mixes on frozen ground or when surface temperatures fall below 37°F.
Self-compacting joint mortars flow into voids naturally when worked across the surface with water and a squeegee. This eliminates air pockets and builds a tight bond without needing mechanical compaction equipment.
Keep the paving surface wet during application, clean off excess material within 5 minutes, and rinse thoroughly. Sweep away remaining fine particles with a damp coconut fiber brush without pooling water. Any slight residual film will weather away naturally under UV light and foot traffic.
Permeable bedding lets water drain freely to the sub-base, preventing standing water, efflorescence, and freeze-thaw damage beneath natural stone, pavers, or tile.
Most joint mortars and bedding systems accept foot traffic after 24 hours. Wait 3 to 7 days for full curing before opening the area to heavy vehicular traffic.
Adding an admixture package to dry, standard bagged concrete introduces synthetic fibers, shrink control, and waterproofing. This increases flexural strength by over 700%, helps seal micro-cracks, and prevents edge breakdown along driveways and walkways.
Apply a bonding slurry to the back of porcelain, natural stone, or pavers before placing them into a fresh mortar bed. This wet-to-wet application creates a high-strength monolithic bond that keeps tiles and pavers from popping loose under heavy loads.
Use clean, washed aggregate between 1/16 in and 1 in in diameter, including glass chippings. Stones can be slightly damp, but dirty, dusty, or soaked aggregate will prevent proper epoxy bonding and weaken the final surface.
