The Most Robust Grass Paving System for Turf Protection

Design grass emergency lanes and permeable parking areas with the industry’s toughest performing porous pavement system. GEOBLOCK®5150 rigid grass pavers provide unparalleled load distribution (up to H/HS25 loading), a high resistance to rutting and torsional loading stresses, and excellent turf protection. Topsoil infill and engineered base allow a high rate of stormwater infiltration and offers an excellent growing medium for quick grass growth and grass life. Less base = less excavation, less fill material, and less cost.

GEOBLOCK porous grass pavers

Best Turf Protection.

Deeper, interconnected cell walls protect topsoil & vegetative root zone from compaction.

Best Medium for Vegetative Growth.

The GEOBLOCK system’s recommended engineered base with 30% topsoil component/70% aggregate retains water to grow grass faster and thicker-drivable in only 2-3 weeks. Grass grows poorly in sand (required infill for weak rolled products) and requires frequent watering.

Higher Stormwater Infiltration.

The GEOBLOCK system has a 5-10X faster percolation rate and better water storage capacity than rolled products as a result of topsoil infill and engineered base vs. sand infill and road gravel.

Optimal Load Transfer.

The GEOBLOCK system’s shared wall structure transfers loads better and is strong enough to drive on pre-filled. Flimsy braces between rolled product cells offer little load support, break easily, cannot be driven upon unfilled, and are prone to rutting if driven on in rain.

Resistance to Torsional Loading Stresses.

The GEOBLOCK system’s shared walls system and interlocking tabs create a framework that resists movement or breakage from vehicle turning stresses and torsional loads. Rolled systems fail under torsional loading.

Less Base Requirements.

GEOBLOCK pavements require far less base depth than rolled systems. Less base = less cutting, less haul in and out, and less expense.

Ships in Stable, Easy to Handle Pallet Cubes

GEOBLOCK units are shipped in stackable pallet cubes and cover a large area per pallet. Rolled products ship only two rolls per pallet standing on end and are not stackable without damaging connectors. Waste is common due to shipping damage.

Topsoil Infill Easy to Install.

The GEOBLOCK system’s topsoil infill is easy to spread with rakes and lutes. Rolled products lift easily when spreading with rakes and lutes as tools catch on rings. Once lifted, complete removal & replacement is required.

Units Lay Flat.

GEOBLOCK rigid paving units lay flat, yet contour to a site. Units slide together quickly, requiring no stakes. Rolled products won’t lay flat due to the rolled product memory making connector clips difficult to connect.

How GEOBLOCK5150 Grass Pavers are Designed to Work for Your Project

Large GEOBLOCK5150 porous paving units are designed for maximum load transfer and support, resistance to traffic stresses and maximum turf protection.

  • Maximizes load transfer and distribution of vehicle loads to 80,000 lbs. provided by large rigid surface area and strong interlocking connections.
  • Reduces overall installation costs by requiring less base depth than lighter-weight or rolled pavement systems.
  • High resistance to movement or breakage from vehicle turning stresses and torsional loads.
  • Uses engineered base (toilsoil/aggregate mix) for a growing medium that encourages deeper root growth, healthier grass performance and water retention.
  • Deeper cells prevent topsoil compaction and vegetative damage caused by repeated loadings.
  • Meet green building goals and earn LEED® credits.

MYTH BUSTERS: Learn the Truth about Porous Pavement Misconceptions

Well-designed porous pavements can out-perform traditional hard-surface pavements such as asphalt and concrete. There are some misconceptions about their cost and performance. Get the facts in the following white papers.

Clogging: Well-designed porous pavement systems resist clogging.

Cost: Overall costs to construct & maintain porous pavements are lower.

Snow Removal: Snow removal on a porous pavement system is easy!

Winter Durability: Properly designed porous pavement systems do not get damaged by the dynamics of freeze thaw cycles.

Winter Maintenance: Properly designed porous pavement systems are not difficult to maintain in winter weather conditions.
