Business owner Natalie Farkas told the the illegal dumping had blocked firms’ only access to their premises, exacerbating problems caused by the existing road closures.
Companies have lost two days of trade as a result of the flytipping, she said.
The firms had already seen trade drop by about 40%, because of the ongoing disruption caused by the housing estate’s construction.
“It’s just been unbearable” she said. “I’ve been trading for 30 years and this is the most stressful it’s ever been,” said Ms Farkas.
“I’ve been through four recessions and I’ve always managed to keep my head in and keep my business going.”
Paul Shaw, managing director for Redrow Midlands, said the housing developer has offered to support the council with cleaning-up the illegal waste as well as supporting with future preventative measures.
