Summary:To provide a block mat that can prevent water from passing through and that can be efficiently manufactured by using hardened concrete blocks.SOLUTION: A block mat has a plurality of concrete blocks that is fixed on a flexible sheet. The sheet includes a base material sheet on the concrete block side, and an impervious sheet on the opposite side to the concrete blocks. The base material sheet is a porous sheet. The concrete blocks, the base material sheet, and the impervious sheet are integrated by using an adhesive. Viscosity of the adhesive at 23°C is equal to or higher than 50 mPa s and lower than 100,000 mPa s.SELECTED DRAWING: Figure 2 【課題】水の透過を抑制でき、かつ、硬化済みのコンクリートブロックを使用して、効率よく製造できるブロックマットを提供する。【解決手段】可撓性を有するシートに複数のコンクリートブロックが固定されたブロックマットであって、前記シートが、前記コンクリートブロック側の基材シートと前記コンクリートブロックとは反対側の遮水シートとを備え、前記基材シートが多孔性シートであり、前記コンクリートブロック、前記基材シート、および、前記遮水シートが接着剤により一体化されており、前記接着剤の２３℃における粘度が、５０ｍＰａ・ｓ以上、１００，０００ｍＰａ・ｓ未満である、ブロックマット。【選択図】図２
