DB Group traded under the Cemfree brand and Pudlo waterproofing products.

Administrators from BDO LLP took charge of the companies last week and the group has ceased to trade.

Latest results for the year to December 31 2022 show DB Group had a turnover of £5.5m generating a pre-tax loss of £170,000 while employing 56 staff,

The results state that funds generated by the other group businesses have “continued to be used to fund to finance Cemfree development and commercialisation, acceleration of which pushed the group into operating losses financed from internal reserves.”
