Deep in the bowels of the earth I break out concrete so I can get a sump in . There’s no way I can get the base ‘smooth ‘ . How best to bed the sump so no sharp bits puncture it ? . Dry sand and cement mix ? - then gently allow water to soak in around the base ?
Better method ?
Keen eyed amongst you will notice that this job was too much for the black and gold team ( Dewalt ) so we called in the Hilti boy . Appreciate Makita users won’t be familiar with that and need to go back to their cocktail at the Pink Flamingo nightclub .
