What Pylon does

Pylon Public Company Limited is a specialty foundation construction company headquartered in Bangkok, Thailand and listed on the Stock Exchange of Thailand (ticker PYLON). Founded in 2002 and operated by the Sangarayakul family, the company provides three core service lines for large-scale public and private construction projects: (i) Circular Bored Pile construction in diameters from 50 cm to 200 cm and depths exceeding 80 meters; (ii) Jet Grouting ground improvement at 200-400 bar pressure, including Soil Cement Columns and localized soil strengthening; and (iii) Diaphragm Wall and Barrette Pile construction with thicknesses from 50 cm to 1.5 m and bearing capacity exceeding 2,000 tons per pile. Its wholly-owned subsidiary Excelon Company Limited provides complementary design, construction, consulting, and architectural services. The company has been recognized three times in Forbes Asia's 'Best Under A Billion' (2014, 2019, 2020) and holds ISO 9001:2015 certification.

The business operates a project-based, competitive-bidding sales motion targeting two primary customer segments: private real estate developers (condominium, hotel, office, and mixed-use projects from developers including AP, Ananda, Asset World Corporation, Pruksa, Major Development, Asset Wise, Eastern Star, and Risland) and government/public sector infrastructure (notably mass transit systems including the Yellow Line). Recent high-profile projects include Porsche Design Tower Bangkok, The Ritz-Carlton Bangkok Riverside (opening 2028), Bangkok Christian Hospital twin towers, and the Hatai Silom hotel complex. Pricing is determined per project on specifications, soil conditions, pile dimensions, and construction methodology rather than fixed tiers.

Revenue is generated almost entirely within the Bangkok Metropolitan Region, with no disclosed foreign operations. The company's record-high backlog of THB 2,200 million as of end 2025 — with management guidance indicating approximately 70% would be recognized as 2025 revenue — points to annual revenue in the THB 1.2-1.5 billion range. Marquee customers span ultra-luxury residential, hospitality, healthcare, and mass-transit infrastructure, with the bulk of recent wins concentrated in Bangkok's high-rise condominium cycle. Distribution is exclusively direct (competitive bidding), and the company maintains a workforce of 800+ engineering staff, project managers, foremen, and administrative personnel.

Products and services

• Bored Pile (Circular Bored Pile) Construction Specialty foundation construction service delivering Circular Bored Piles with diameters from 50 cm to 200 cm and depths exceeding 80 meters, used for foundations of large-scale structures in urban areas where driven piles are not applicable due to vibration and transportation constraints. Causes no lateral movement of soil underneath that may affect nearby structures, with less noise pollution and ground vibration than driven pile alternatives. Target customers are private real estate developers and government infrastructure clients.
• Ground Improvement by Jet Grouting Foundation strengthening service that increases soil bearing capacity and prevents lateral soil movement by injecting cement grout at high pressure between 200 and 400 bars. Includes Soil Cement Column technique for complete soft soil layer improvement and Localized Soil Improvement for specific areas. Target customers are real estate developers, infrastructure project owners, and public-sector clients requiring soil stabilization.
• Diaphragm Wall / Barrette Pile Construction Underground reinforced concrete wall construction serving as load bearing and retaining structure to prevent lateral soil movement, with thicknesses from 50 cm to 1.5 m and water-resistant properties. Barrette piles are cast-in-place reinforced concrete piles with rectangular shape (cross section width 60 cm to 1.5 m, length 2.5 m to 3.0 m, depth exceeding 60 m) suitable for high bearing capacity of more than 2,000 tons per pile. Target customers are real estate developers and public infrastructure clients.
• Design, Construction, Consulting and Architectural Services (via Excelon Company Limited) Complementary design, construction, consulting and architectural services for buildings and structures, delivered through Pylon's wholly-owned subsidiary Excelon Company Limited (registered capital of THB 20 million). These services complement Pylon's core foundation construction business by providing upstream design and architectural capabilities to the same developer and public-sector clients.

• Bauer AG: German global foundation specialist with deep expertise in bored piles, diaphragm walls, and ground improvement — a direct international peer in Pylon's core construction methodologies.
• SEAFCO Public Company Limited: Thai SET-listed specialty foundation contractor providing bored piles, diaphragm walls, and ground improvement services — the closest direct domestic competitor to Pylon in the Bangkok market.
• Soletanche Bachy: French international foundation specialist and Pylon's historical partner (2004 Samlae Water Treatment Plant cooperation). Directly comparable in diaphragm wall and deep foundation methods; also a potential global competitor on Thai infrastructure tenders.

Broad incumbents

• Syntec Construction Public Company Limited: Thai SET-listed building and civil contractor covering commercial, residential, and infrastructure construction. Comparable to Pylon as a Thai contractor serving similar real estate and infrastructure clients, but with a much broader portfolio.
• CH. Karnchang Public Company Limited: Large Thai SET-listed infrastructure contractor focused on mass transit, expressways, and energy projects. Overlaps with Pylon on government infrastructure foundation work but operates as a broad general contractor rather than a foundation specialist.
• Italian-Thai Development Public Company Limited: Thailand's largest Thai-owned construction company with diversified infrastructure, building, and energy project capabilities. Overlaps with Pylon as a Thai general contractor serving public and private clients.
• Pre-Built Public Company Limited: Thai SET-listed general contractor specializing in commercial buildings and industrial construction. Competes with Pylon for the same Bangkok developer clients but without Pylon's deep-foundation specialization.
• Unique Engineering and Construction Public Company Limited: Thai SET-listed engineering and construction company focused on power plants, industrial facilities, and infrastructure. Comparable Thai contractor serving large-scale project clients but with a different end-market mix than Pylon.
