PREBENCHED SYSTEM

Custom Manufacturing Solutions by Leko Precast Ltd

As civil construction standards continue to rise, the need for smarter, more efficient infrastructure solutions is undeniable. At Leko, we’re leading the way with the PERFECT manhole system—engineered for precision, guaranteed watertightness, and unmatched ease of installation.


Originally developed by Schüsselbauer Technology in Austria, this state-of-the-art system was introduced to Western Canada in 2017, when Leko became the exclusive manufacturer and supplier in the region. Since then, we’ve ramped up production to meet growing demand and have received outstanding feedback from contractors, engineers, and municipalities alike.


Our manhole bases are manufactured with exceptional accuracy and consistency, available in a wide range of sizes including 42", 48", 60", 72", and 96", with custom options also available. Every unit is designed to streamline installation, reduce on-site labor, and ensure long-term performance in the most demanding conditions.


At Leko, we’re not just building manholes—we’re building the future of underground infrastructure.

  MONOLITHICALLY POURED

Perfect bases are poured upside-down over assembled channels with high-performance self-consolidating concrete. This ensures a watertight base with seamless channel intersections.


SAFE AND EFFICIENT 

Perfect bases can be produced quickly and accurately. Onsite costs are reduced as there is no need for onsite benching of manhole bases. It also facilitates a safer work site, as there is no need for coring barrels onsite and the associated exposure to hazardous silica dust.


COMPATIBILITY 

Bases are available in all of our standard manhole diameters, and collars are compatible with our barrel risers and Tylox SuperSeal gaskets. A complete system, from invert to rim!


CUSTOM MADE 

Every manhole is designed and built to the individual specifications and requirements of each project. Pipe types, sizes, angles, and grades are customized for  installation. 


GASKETED OPENINGS 

Perfect bases are manufactured with openings for SDR, Ultra-Rib, Kor-Flo and HDPE pipes. Leko Precast offers drop-in services and catch basin leads as an added value to our customers.


ACCURACY 

Because channels are mechanically programmed and robotically cut, we can reduce many problems commonly associated with hand-benching. Our bases will not puddle, and flow is optimized even at low pipe grades.


FULL SERVICE TAKEOFFS

Our knowledgeable service personnel will send complete takeoffs for approval.  Send the construction drawings to our office, approve, and arrange delivery of your order!
