Filament polyester geotextile is the kind of synthetic and permeable material used in civil construction projects to improve soil characteristics. The application for filament polyester geotextile in the road construction projects grows annually, geotextile fabric is widely used to reinforce the soil by adding tensile strength, it also can be used as a rapid dewatering layer in the roadbed or railways. BPM filament polyester geotextile is used to separate the individual soil layers without impeding groundwater circulation where the ground is unstable. Geotextile fabric can make poor soils more suitable for construction, since they have the ability to separate, filter, reinforce, protect and drain soils.
BPM Filament polyester geotextile is used as a fast dehydration layer in the roadbed road construction , and it needs to maintain its permeability without losing its separation function to prevent soil erosion and road gene rain from washing and collapsing.
Case Study:
- Location – Lamu
- Products – 250g/㎡ filament polyester geotextile
- Application – Road construction
BPM Lamu Partner is CALE INFRASTRUCTURE CONSTRUCTION COMPANY Who got the A14 road Lamu -Garissa road construcion project . Total is 467 kilometers. The Main road is Mokowe-Hindi-Bodhei-Ijara-BuraEast-Garissa. Total is 257km. They sent us inquiry for fliament polyester geotextile of specification for 250gm, and minimum Tensile Strength＞16kn/m, the minimum elongation at break＜65%. Our filament polyester geotextile is produced from polyester long fiber forming into net and consolidation with three dimension structure . it is a kind of new material in geotechnical and engineering project. Except for its good mechanical properties of tensile strength and puncture resistance, it also has good drainage ability, acid and alkali resistance and anti-aging. The wider opening size allows it has good permeability and filtration. The Standard and grade must up ASTM 04595. They required 400,000 square meters geotextile fabric, and the order was divided into 6 sections, the first section was 90,000 square meters. At the beginning the CALE INFRASTRUCTURE CONSTRUCTION COMPANY visited BPM company. BPM has its own 16,000 square meters factory and advanced production line of geomembrane and geotextile gave them professional impression. Before we signed agreement they asked us to offer product brochure, ISO Certificate, SIRIM Certificate, Test Certificate, Project References and material safety date sheet, all their requirements were sent by email. Finally, we we signed the order and accepted the deposit. BPM sped up the time to supply the Section 1 of 40hq*3 container within 14days to catch up for required deadline .

Garissa road construction project began with the ground breaking held in Lamu, Kenya, in August 2019. The construction section of our partner department is CH80+000-CH160+000. There were few structures in this section, no bridges, no asphalt surface, and mainly earthwork and culvert construction. The standard width of the top floor of the road was 11m, the two-way two-lane road was 7m, the width of the soil shoulders on both sides was 2m, the subgrade slope ratio was 1:2, which was a Class II highway. The standard width of the top floor of the branch road was 8.5m, and the two-way two-lane 6.5 was adopted. The width of the soil shoulder on both sides was 1m, and the subgrade slope ratio was 1:2. Lamu is located in the eastern part of Africa, with the equator traversing the central part, and is located in the tropical monsoon zone. It has a savanna climate, divided into rainy and dry seasons. Affected by the Indian Ocean monsoon and altitude, the coastal areas are hot and humid all year round, and the plateau areas have a milder climate with unclear four seasons. The groundwater along the line is mainly loose layer pore water. The loose layer is thick, mostly black clay, with poor water permeability and high water content in the rainy season. Groundwater mainly comes from atmospheric precipitation replenishment and surface runoff infiltration, and the discharge mainly depends on natural terrain diversion. The construction area of the bidding section is located in southeastern Kenya, with an altitude of 250-350m. It has a tropical rain forest climate. The year is roughly divided into two seasons: rainy season and dry season. The rainy season is from April to July and October to December each year, and the rest is the dry season. . Among them, the heavy rainy season is from April to July, and the light rainy season is from October to December. In the rainy season, the rainfall is heavy and the rain is strong. In a short time, a large amount of rainwater can be collected on the line to form a river; there is occasional rainfall in the dry season, and the rain is strong, Water catchment and discharge are faster. The temperature is 28℃～34℃, the annual average temperature is higher than 30℃, the temperature difference is small, and it is humid and hot. BPM Fliament Polyester Geotextile played an important role for the improve the stability of slope and reinforcement soil, avoiding water and soil loss and soil frozen.
BPM Fliament Polyester Geotextile Features
- Increase the stability of gravel slopes and reinforced soil to prevent soil erosion and frost damage at low temperatures
- The isolation layer between artificial fill, rockfill or material field and the foundation, isolation between different frozen soil layers, filtering and reinforcement effects
- The filter layer around the drainage concealed pipe or the gravel drainage ditch
- Vertical or horizontal drainage inside the earth dam, buried in the soil to dissipate pore water pressure
- Highways (including temporary roads), railways, embankments, airports and other projects are used to strengthen weak foundations
BPM filament polyester geotextile is the continuous filament needle punched non-woven geotextile made from polyester virgin material, formed by the process of needle punching and thermally bounding, offers optimum performance per unit weight. BPM filament geotextile provides effective and economical solution of separation, filtration, drainage, protection and reinforcement functions for engineering projects. The filament is quickly obtained in the pavement base of nylon geotextile, it needs to maintain its network, while not losing its exempt function to prevent water and soil geotextile, and use it with foundation, soil construction, rock, soil or other materials. The characteristics of soil formation, protection, drainage, isolation, filtration, and containment. The filament polyester geotextile is cost effective geosynthetic material suitable for isolation layer of artificial backfill soil stone with foundation and different tundra. Wisdom and other functions have improved the quality of the highway, prolonged the life of the highway, shortened the construction time, and lowered the project cost.
