Paving stone for granite pavers - Granite Paving Stones

Desenvolmente

The company "Desenvolmente" refers to theextraction, processing and marketing of ornamental rocks.
Thequarryis located in northernPortugal, the area where thegraniteis abundant and of excellent quality.
Granite colors: yellow, gray and mixed.

• Cubes and Setts

Hardwearing and extremely durable, graniteis the ultimate paving product.Unafected by frost or heating,granite resiststo the stress caused by vehicular traffic and environmental pollution. That makesgranite cubesand setts ideally suited for use aspaving in pedestrian areas, driveways and traffic roads.Cubes and setts are most commonly suppliedin bulk, on board of conventional vessels. Alternatively, it can be packed in wooden crates or big bags.

• Kerbs

The high "breaking load point" and the extremelylow water absorption of Portuguese granitemake it incomparably suited for kerbing. Specialized in aesthetically appealingrough finishing,Desenvolmente is able to supply any measure request to match any specific requirement.

• Slabs

Timeless beauty and high wear resistance ofgranite slabsmake them ideal forindoor and outdoor pedestrian areas.Wheter withsawn or split edges, slabs can be provides indifferent dimension. Being a major factor for outdoor use, the slippery resistance is obtained through surface treatment:flamed, bush-hammered, sand-blasted, etc.

• Cut-to-Size

In order to allow the satisfaction of the most demanding individual specification requirements to suit any project, Desenvolmente is able to supply to its clients the required granite products whatever are its finishing and level of transformation – A high skilled team of stone masons can feature anycut-to-size order.

The granite cubes "5x5x5 and 10x10x10" satisfy the following conditions:

a) the stone is granite tough, homogeneous, uniform gray color, fine-grained tight
and the sound of the hammer blow.
b) has substantially straight edges and squared.
c) has at least two flat sides and desempenadas.
d) has the dimensions of 0:10 * 0:10 * 0:10 m (0.01 m with a tolerance of less and
to 0.02 m or more) or 0.05 * 0.05 * 0.05 m, depending on whether the paving bays
parking and / or roadway, or walks respectively.

Example of work with gray granite 10x10x10

1 - OPENING OF "BOX"
Will carry pre-opening box with the depth from 0.37 m to be
regularized and compressed properly by means of a mechanical compactor.
The case must stand on a surface parallel to the floor that will provide after
completed and will therefore have an identical cross slope (3%).

2 - LAYER BASE
Is applied a layer of material of large particle size 0-40 mm with a thickness of
0.20 m, once compressed and regulated by means of a mechanical compactor.

3 - CUSHION SAND
Will be spread over the base layer of a medium sand with 0.06 m thick,
serve as a bed for laying granite cubes.

4 - SETTLEMENT OF CUBES
The laying of the cubes is performed by placing the stones in rectilinear rows of
so that the joints of each row remain mismatched with those of adjacent rows.
Completed the settlement of the cubes will proceed to fill the joints with sand.
To that spreads a layer of sand with an average of about 0.02 m. Thickness on the
sidewalk, forcing the penetration joints with the use of brooms.
Then it will make the compaction of the floor using a mechanical compressor,
preferably vibrator.
