John Engwar is the owner and president of Groundscapes Express, Inc., he has been providing innovative, environmentally responsible erosion control, stormwater management, and ecological landscape solutions since 1998. His work is rooted in stewardship, clean water protection, soil health, and the belief that construction and land care can work with nature rather than against it.

A pioneer in the use of biodegradable compost-based erosion control products, he patented the FilterMitt system and helped introduce compost tubes as a sustainable alternative to synthetic erosion control materials. His company was among the first in New England to use compost products extensively for erosion control and stormwater management, helping reduce runoff, stabilize slopes, protect soils, and improve water quality without leaving plastic waste behind.

Groundscapes Express has worked across highways, railroads, parks, athletic fields, golf courses, residential and commercial developments, municipal projects, and sensitive environmental sites throughout New England. The company’s work includes erosion control, stormwater treatment, invasive plant management, native planting, soil restoration, compost applications, ecological landscape design, and sustainable construction installations.

He has collaborated with MassDOT, engineers, developers, regulators, inspectors, and municipalities to create practical solutions that meet environmental standards while improving long-term site performance. His approach combines field experience, compost science, native plant knowledge, invasive species management, and a deep commitment to protecting natural resources.

With decades of project experience, he is recognized as a leader in biodegradable erosion control, sustainable site work, water conservation, and ecological land management. His mission is simple: build better landscapes, protect cleaner water, restore soil biology, and leave the land healthier than he found it
