LarKen Precast, a division of CXT®, manufactures engineered precast concrete products. We specialize in precast concrete septic tanks, pump tanks, sand oil traps and grease interceptors, catch basins for storm, wastewater, irrigation, and electrical applications, as well as manhole risers, bases, and eccentric cones. Other products that we offer include stair treads, light post bases, parking curbs, and other custom projects.

Our septic and pump tanks are approved by the State of Idaho Department of Environmental Quality (DEQ) as well as the Oregon DEQ. We make special concrete tanks for extended treatment systems including the BioMicrobics Fast® Systems.

Our designs meet requirements for Uniform Plumbing Code, Idaho Standards for Public Works, Ada County Highway District Supplemental, the City of Boise, and other municipalities in the area.

LarKen delivers products throughout Idaho and eastern Oregon. Delivery includes tank setting in most instances. We strive to “Buy Idaho” and “Buy America.”

At LarKen we batch our own self-consolidating concrete using Portland cement, quality washed sand, aggregates, and Grace water-reducing/plasticizer additives. Our compression strengths exceed standard specifications, and we use rebar to assure strength in our quality products. Our quality control follows National Precast Concrete Association guidelines, and our products are poured within twenty minutes after mix. We reclaim the wash water used and take every opportunity to reclaim, recycle, and reuse other aggregates and recyclables.

We assemble components for on-site pump systems and lift stations and offer a large number of quality wastewater related products including, Orenco® Systems products, ADS pipe, Polylok™ polyethylene products, ADS Arc 36™ and gravelless domes, geotextiles, and most common pipe and fittings for the wastewater industry.
