Erosion Control Pavement, Pavement for Ponds and Banks

System for reinforcement of banks and bottoms of rivers, streams and dams.

TRI-LOCK blocks are suitable for unstable walls of riverbeds that are washed away with water.

The TRI-LOCK system is a large-scale load pavement that is dry-assembled. The area of the pavement consists of two elements that are repetitive – a lock and a key that prevents any kind of movement. TRI-LOCK perfectly traces the terrain and has a high stability in waterway regulation. It can be grassed. The system can be used for parking areas, floor protection levees and polders and retention reservoirs and areas.

“I would like to say a few things about the Tri-Lock material that we know very well. We hage used the system for two job orders – thanks to the satisfaction of the previous investor and its good erosion control properties. We used the system for these constructions: Okrouhlo u Prahy – used due to the large angle of slope of the retention reservoir. We had no problems with the installation. Svitavy Composting Plant – again thanks to the good erosion control properties.”
Březina Jan, BETA-PROJEKT s.r.o., Svitavy
“I would like to thank you for Tri-Lock – we used it to “pave” the bank of the stream and we were thrilled how easy it was to install in the difficult-to-access terrain.”
Petr Kořínek, České Budějovice
"Our municipality has decided to reinforce the challenging banks of the adjacent river by the Tri-Lock building elements. I think we cannot have better choice. Now the challenging points are "closed" and so-far we have detected no problems, with which we usually met in history, such as landfall at the bank to the river. Our thanks belong to you."
