Slope Stabilization and Reinforcement

Prevent erosion, reduce risk, and protect your slope with minimal disruption.

Our Gripple Terra-Lock® system delivers high-performance slope stabilization without the cost and complexity of traditional methods. 

Both naturally occurring and cut slopes for roads or infrastructure are prone to erosion, slippage, or even full-scale failure.  

That’s why groundworks and civil engineering contractors turn to Gripple. Our Terra-Lock® range offers a smarter, faster way to stabilize slopes and control erosion without the need for concrete, piles, or heavy machinery. 

Our Terra-Lock® anchors are driven deep into the slope and secured with a surface plate, instantly reinforcing the soil by connecting it to more stable ground beneath. Combined with Terra-Lock® Pins and geogrid erosion control matting, the system prevents shallow and deep plain failures while allowing vegetation to grow and strengthen the surface over time. 

Unlike traditional hard-armor methods, Gripple’s solution is lightweight, discreet and doesn’t disrupt the environment. You’ll save time on install, reduce material costs, and get long-term performance up to 32 kN of holding force, depending on the soil type. 

From cut slope stabilization on highways to shallow plain slope reinforcement on embankments, our system is compatible with over 60 leading TRM and geogrid slope stabilization products. Installed with just hand tools, no heavy plant or pre-groundworks are required, which saves contractors time and money while delivering immediate performance. 

Manufactured in the US and UK, backed by technical support, and trusted by contractors across the globe, at Gripple we make slope stabilization simple.

            “Using the Gripple Terra‑Lock™ System made securing the HPTRM a smooth and efficient process. The speed of installation, combined with reliable anchoring, allowed the slopes to stabilize quickly and vegetation to establish—restoring the canal and protecting nearby property lines.”

Gripple Terra-Lock® can be used for both permanent and temporary stabilization projects, depending on your requirements.  

											

										    
																					

									


								

							

													

								
								


									

										

											

												
Because the system can be installed by hand, it’s ideal for remote or difficult-to-access locations where heavy plant access may be limited.

											

										    
																					

									


								

							

													

								
								


									

										

											

												
No, once vegetation establishes over the matting, the system becomes virtually invisible, making it ideal for environmentally sensitive or aesthetic landscapes.

											

										    
																					

									


								

							

													

								
								


									

										

											

												
All Terra-Lock® products are manufactured in the US and UK to the highest quality standards.
