Lerma Rectangular Concrete Paver - 6 and 8 cm for walkways and light traffic
Lerma Paver: the classic rectangular paving block
The Lerma Paver is the classic plain rectangular paving block, in 20x10 cm pieces with a thickness of 6 or 8 cm, and with the complementary Half Lerma 10x10x8 cm piece to finish edges and borders without cutting. Made of concrete to the UNE-EN 1338 standard.
✅ Advantages
Universal format: the 20x10 rectangle can be laid in rows, staggered, herringbone, or basket-weave patterns without needing special pieces.
Two thicknesses: 6 cm for pedestrian use and light traffic; 8 cm where vehicles will pass.
Finishing piece: the Half Lerma 10x10x8 solves edges, junctions, and direction changes without cutting pavers.
Wear: class 4 I, Xi<20 mm. Absorption: class 2B, X8<6%.
Intended use: pedestrian use, areas subject to vehicle traffic, and roofs.
🧰 Installation
Excavate the bed and compact the natural ground until it is firm and has the drainage slope.
Spread and compact a 15-20 cm base of crushed aggregate in pedestrian areas, and 25-30 cm if vehicle traffic will pass.
Lay a 3-5 cm bedding sand layer, leveled with a screed and without compacting.
Lay the pavers dry, starting from a straight edge, mixing pieces from several pallets at once.
Finish the whole perimeter with a curb or concrete edging: without confinement the pavement will spread apart.
Sweep silica sand over the joints, run the vibrating plate with a rubber mat, and repeat the sand sweeping a few days later.

💡 Professional tip: always order 5-7% extra material for cuts, edge pieces, and breakages: replacing a loose pallet months later almost never matches the tone. During installation, mix pieces from three or four pallets at a time, because each batch has its own shade, and laying pallet by pallet will leave the floor blotchy. And don't overlook the thickness: 6 cm is for pedestrians and light cars; as soon as loaded vans or trucks come in, go for 8 cm on a well-compacted crushed-stone base. It is the most expensive buying mistake in this family.
