DGB Road Base (20mm)

DGB (Densely Graded Base) is similar to Standard Road Base but a cut above, as it is compliant with RMS specification 3051 and suitable for use a road base material under bitumen, in developments, sub-division, council roadways and so on. It is sized at '20 mm minus', which means it ranges from 20 mm down to dust in particle sizes. Get price

The Complete Guide to Horse Paddock Footing – Lighthoof

Course angular rock is often found as a base, or as the entire footing material in horse paddocks and gate areas. This type of rock typically has particles that are about 1-2" in diameter and fairly uniform in size. It's made in a quarry by crushing larger rocks into smaller ones. Get price

The best foundations for a summer house

Aug 18, 2014The vast majority of GardenLife's buildings come with a pressure treated timber base, but one of the fundamental rules for any garden building is that you need firm, level foundations onto which you can secure your base. If the ground beneath the summer house or log cabin is uneven, the screw holes on the walls may not meet up properly, and the walls may distort, with individual timbers Get price

material and the smallest sized material. The base course requires of the material to pass a 1 inch sieve, but allows up to 20% of the stone to be retained on the 3/4 inch sieve.While this could make excellent base gravel, it would likely perform poorly if used as gravel surfacing. There would be too much large stone resulting in very Get price

Subbase (pavement)

In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement, but it is necessary for surfaces used by vehicles. Subbase is often the main load-bearing layer of the pavement.Its role is to spread the load evenly over the subgrade. Get price
