Concrete and Masonry Sand

Description

Primary and secondary extraction of concrete and masonry sand is limited to those areas where there is sufficient coarse sand that can technically be extracted. According to the TNO report Regional Soil Opportunities Map Zuid-Holland (December 2000), large differences occur in the thickness of the recoverable concrete and masonry sand. The largest thicknesses (20 to 40 meters) are found in an elongated strip that runs from the Alblasserwaard, the Krimpenerwaard, the Zuidplaspolder, the surroundings of Pijnacker and Delft to Rijswijk. In an elongated strip from Bodegraven to Leidschendam, the recoverable sand reaches thicknesses between 15 and 35 meters. Northeast of Leiden, the concrete and masonry sand in the recoverable package also reaches large thicknesses (15 to 35 meters). In the rest of the research area, the thickness of the concrete and masonry sand largely varies between 0 and 15 meters. In parts of the province there are insufficient hard data to be able to make a statement about the thickness of the extractable packages of concrete and masonry sand, especially northeast of the Zevenhuizerplas and in the northeast of the province. Contiguous loam, clay and peat layers were not found in the recoverable package. Locally, in the recoverable package gravel layers occur, which can reach a thickness of several meters. West of the line Alphen aan den Rijn - Capelle aan den IJssel - Strijen layers of shells appear in the recoverable package. In general, the shell content of these layers is not high. The thickness of the covering package in South Holland increases from east to west from approximately 4 meters to more than 20 meters.
