ABEL Clay offers a better block, a superior block as compared to alternative building materials. In addition to clay’s natural properties, which make it stronger than other building materials, ABEL Clay’s new factory, TK4, the most technologically advanced clay facility in the Western hemisphere, enables a quality manufacturing process.

Why choose ABEL Clay?

Strength you can trust

Clay blocks possess more than enough strength to meet the new building requirements and codes.

Foundation that lasts a lifetime

Clay foundations will not deteriorate over time due to acids and alkaline in the surroundings and saltwater.

Reduction in labour Cost

ABEL Clay blocks are significantly lighter than concrete.

Reduced Downtime

Clay absorbs less water and dries faster, so there is less downtime during construction.

Thermal resistance

Hollow clay blocks provide far better thermal insulation than any other comparable material – 70% advantage in thermal resistivity when compared to concrete blocks (IEEE442 and ASTM5334 tests).

Fire resistance

Clay is non-combustible and as such cannot contribute to the start or rapid spread of fires – clay walls obtain maximum ratings.

Sound Resistance

Since hollow clay block walls and partition are lightweight and honeycombed with cells, they are highly resistant to the transmission of sound.
