I cleaned this drive less than 3 months ago. It still looks great, apart from all the weed regrowth. Now i soaked all bricks etc with strong hypo as well as turbo nozel etc etc as we do.
I thought the hypo mix would kill at the roots as well and perhaps slow down any re growth atleast. Or is it down to the kiln sand im using. I know theres sand out there with weed prohibitors and they may kast a little longer before regrowth, but they work out quite expensive.
Sadly this is a client of mine for regular other services and so it will do my nut in! The client hasnt said anything it just makes me wonder about my other clients work that ive done.
Any answers guys or is it a case of using a sealant, but is that effective for the cost??
