Specialist Concrete

Stevenson Concrete supplies a wide range of high-quality specialist concrete products to suit the needs of your project.

Pervious Concrete

Pervious concrete is a special type of concrete with a high porosity used for concrete work applications that allows water to pass through, thereby reducing the runoff from a site and allowing groundwater recharge or peak flowwater retention. The high porosity is through an interconnected voids between the aggregate particles.

Thermal Backfill
Concrete over cable

High voltage materials when buried underground generate considerable amounts of heat, which must be dissipated by using a quality thermal backfill.  The TR results obtained are less than 0.

No Fines Concrete

Stevenson No Fines concrete is a specially designed concrete with a specified void content that allows large volumes of water to quickly fill the voids between the aggregate particles. It is formed by eliminating the fine material from the regular concrete mix.
